Gas mileage comparison 351C vs 400....

Hey all,
I used to run a 351 Cleveland in my car, it had been tricked up a bit. I was wondering how the gas mileage of that will compare to a 400?
I know the 77 F150 will be heavier, and less aerodynamic...but will they be hugely different?
Thanks,
Shane

Probably in the 10-12 mpg range for a carbureted 400, if your lucky.
